Deciding whether to invest in Bitcoin? Here are the other big names in crypto

Cryptocurrencies have hit new all-time highs this month as they become more appealing to mainstream investors.

Cryptocurrencies have hit new all-time highs this month as they become more appealing to mainstream investors.

Bitcoin, the most popular digital currency, soared to a new all-time high of nearly $70,000 per coin this week. It has climbed almost 125% this year, while the good old S&P 500 is up less than 24%.

The first Bitcoin ETF started trading last month, allowing investors to get in on the crypto craze without actually buying the currencies outright.

Clearly, the crypto craze is here to stay. But there are big questions about what kind of regulation might be in the works for the asset class. And even some of Wall Street’s biggest names, most notably JPMorgan CEO Jamie Dimon, remain skeptical of cryptos’ staying power.

For investors new to the space, the myriad of coins can be daunting. Here’s an overview of the five biggest cryptocurrencies.


Bitcoin has always been the biggest player in the cryptoverse, and is now worth more than $1.2 trillion in market capitalization, according to CoinMarketCap.

Its new all-time high makes it more than 10 times more valuable per unit than the next biggest crypto.

Launched by an anonymous creator in 2009, the digital currency runs on blockchain technology — another crypto buzzword. Essentially, the blockchain is a decentralized ledger system where records of transactions are stored. That’s the key difference between bitcoin and traditional fiat currencies like the US dollar or the euro, which are controlled by central banks.

Many bitcoin bulls call it a “store of value” — a label historically reserved for safe haven investments like gold — and argue that that the digital currency is a good tool to hedge against inflation, something a lot of investors are worried about at the moment.

But it’s also prone to wild swings in value, including flash crashes.

Part of bitcoin’s value is determined by the finite number — 21 million — of coins that can be created. Not all of them are in circulation yet. Bitcoin “miners” use computers to solve complex puzzles to create a new block on the chain. That process is in turn rewarded with bitcoin, though the reward halves for every 210,000 blocks mined.

These “halving” events have in the past led to volatility in the bitcoin price. And the mining process eats up a lot of computing power and electricity, which has led to concerns about bitcoin’s environmental impact.


Ethereum is the perennial second fiddle of the crypto world.

But it’s still one of the most popular and valuable digital currencies, and with a market cap of nearly $560 billion, it’s firmly in second place behind Bitcoin. Its all-time high was just below $5,000 this week, according to CoinDesk data.

The value of Ethereum, launched in 2015 as open-source blockchain-based software with its own cryptocurrency, has risen more than 540% this year. It’s been boosted by investors who believe Ethereum, also called Ether, will be key for decentralized finance including smart contracts and NFTs (non-fungible tokens).

The software was created to expand the use of the blockchain beyond bitcoin so it could be used in wider applications, which makes it more than merely a cryptocurrency.

And unlike bitcoin, ether supply isn’t capped. New tokens are created constantly through a similar mining process.

Binance Coin

The third-largest crypto, with a market cap of more than $100 billion, Binance Coin, or BNB tokens, is a different beast. A product of the Binance Exchange, the largest cryptocurrency platform by volume traded, it was created as a means to pay for fees on its own platform.

It has a cap of 200 million BNB tokens, but tokens are regularly destroyed — or “burned” — to reduce the total supply and stabilize the their value over time. That means that people’s Binance holdings shouldn’t fluctuate in value as much as other cryptos.

Binance Coin is also different in that it can be exchanged only into other cryptocurrencies, and not into dollars or any other fiat currency.

Last summer Binance hired Brian Brooks, who was acting head of Office of the Comptroller of the Currency during the last eight months of the Trump administration, to head its US business. Brooks resigned in August after only a few months on the job. He is now the CEO of Bitfury, another bitcoin mining company.


Tether has moved up to rank fourth among the five biggest digital currencies, with a market cap of nearly $74 billion.

It’s an example of a so-called stablecoin because it is pegged to the US dollar. This keeps Tether relatively stable compared with other cryptocurrencies, which can be very volatile. At its 2014 creation, the value of each token was set at $1.

While regulatory uncertainty is a big topic for all cryptos, stablecoins might be at particular risk: Earlier this month, the President’s Working Group on Financial Markets, the Federal Deposit Insurance Corporation and the Office of the Comptroller of the Currency all urged Congress to slap bank-like rules on stablecoins. The regulators worry that the digital assets aren’t in fact stable and could hurt investors and create financial stability.


Solana is basically a competitor to Ethereum. It’s a blockchain network with its own digital currency called Sol.

Only as old as the pandemic — Solana was founded in March 2020 — the crypto has skyrocketed more than 10,000% over the past year, according to data from CoinGecko.

That’s right: The crypto went from being worth a modest $2 per unit to a value over $200, bringing its market cap to more than $70 billion and outpacing fellow cryptos Cardano and XRP, which have also spent time in the top five.
